Self-consistent covariant description of twist-3 distribution amplitude of a pseudoscalar meson in the light-front quark model

Published 11 Dec 2014 in hep-ph | (1412.3556v1)

Abstract: We discuss the light-front zero-mode issue in the light-front quark model prediction of the twist-3 distribution amplitude of a pseudoscalar meson from the perspective of the vacuum fluctuation consistent with the chiral symmetry of QCD.
